1 i The present invention relates to a chair which is expresslyconstructed for use by sick andA bedridden persons, the same `beingespecially and suitably designed to occupy a satisfactory position atopthe mattress, whereby to provide a con, venient chair and support forthe occupant of the bed. y

Although the chairv was expressly constructed, at the time ofinception,` for use in connection with hospital beds, it is obviously,and equally well ladapted for use in the home, and places ofconvalescence and recreation Brieliy, the preferred chair ischaracterized by. a suitable frame which is adapted to t firmly andhorizontally on the mattress, this` part of` the structure beingprovided with conning sides and armrests .and being .expressly designedto accommodate a tiltably adjustable back-rest. More explicitly, the`chair proper comprises a pair of spaced, parallel, horizontal rails torest upon themattress, uprights connected to and rising from said rails,and auxiliary rails above the mainbase rails, said auxiliary railsconstituting side guards and arm rests, and being constructed at theirrear ends to appropriately coniine and adjustably support a'back-rest,the latter hingedly connected to the rear end portions of the base rail.

Other objects, features and advantages of the invention will become morereadily apparent from the following description and the accompanyingillustrative drawing.

In the drawing, wherein like numerals are employed to designate likeparts throughout the views:

denoted at B. The back-rest is the simplest ofl the two parts in form,and comprises a frame embodying vertical members 6, top and bottom v 4Claims.

members 'I and 8` and suitablyfiattached andV spaced slats 9. The sidemembers are` mortised, as shown in Figure 4, to accommodate, ineachinstance, the projecting portion I0 of a latch plate II. `The latter isscrewed orotherwise fastened in place and the part I0 issocketed.toraccom-f. modate a coil spring I2. The spring servestoprol ject thekeeper endI3 of the head-equipped latch pin or plunger I4. i The chair Acomprisesa pair Iofspaced parallel bottom or base rails I5, these `beingadapted to; sit flat on the mattress I6, as shown in Figure .2.l

Inwardly of the rear end is a substantially U- shaped strap II havingits outer end portions secured to the top surfaces` ot thenbase'railsJS,the free ends being `upturnedtoprovide accom-L modation ears or lugs I8to which the hinge Pintles I9, on the back-restB, are connected. ThisU-strap I'I is the `main means lor" connecting the` rails together.

I now call attention tota plurality of uprights 20, 2| and 22, as seenVin Figurex2,'these hav-` ing their inner,- laterally-directed, lowerends .23A riveted or otherwise secured .to longitudinallyspaced portionsofthe respective baserails 1I5.\

Next, I call attentionfto theupper lor auxiliary chair rails 24. Iprovide a pair of these disposed in parallelism and of angular form. Thehorizontal, inturned anges are denoted at 25 and are reinforcingelements as well as ledges. The upper ends of the uprights 20, '2l and22 are riveted to the vertical anges of said rails 24. As seen in Figure5, a slide board or suitable plate 26 is provided, it being of generalrectangular form, this part serving as a general utility table. Itsouter, transverse ends slide on the ledge flanges 25 and said flanges4have channels 21 formed in their under surfaces. The channelsconstitute keyways and serve to accommodate the keys or detents 28carried by the keying cleats 29 bolted or otherwise secured to the undersurface of the table board y2li. It will be noted that these flanges 25stop short of the point occupied by the back-rest B when said back-restis in perpendicular position, as shown in Figure 2. Thus, the rear orterminal end portions of the rails constitute adapters and are denotedby the numerals 30. The curve slightly down and have their free endsinturned and riveted to a cross-strap 3|. This serves as a rest for therearmost and inclined position of the back-rest, as shown at the rightin Figure 2. It is also to be noted that these downturned end portions30 are provided with longitudinally spaced apertures which constitutekeepers 32 for selective reception oi the ends I3 sits directlyA onlthemattress between said,` rails.,y The uprightsandauxiliary side railsconstitute;

coniining sides as well as arm rests toaid in supporting'tmpatient. Thetable 26 comes in handy for reading, eating, and other useful purposes.`The back-rest is lightweight, yet sturdy, and easy to adjust, making itpossible for the patient to recline to a position of requisite comfort;

Finally, my improved chair, with backrest and side arms, can be used toadvantage as a convenient support for patients that need a sittingposition in bed, such as with heart disease. The side arms serve as faprotection against falling sideways when'patients are unconsciousorvsemiconscious. I f

It is thought that persons skilled in the art to which theinventionrelates will be able to obtain a clear understanding of theinvention after considering the. description in connection with thedrawing. Therefore, a more lengthy. description is regarded asunnecessary. Y I
